Polyelectrolytes are polymers with repeating units of ionizable groups coupled with counterions. Recently, polyelectrolytes have drawn significant attention as highly promising macromolecular materials with potential for applications in almost every sector of our daily lives. Dyes are another class of chemical compounds that can interact with substrates and subsequently impart color through the selective absorption of electromagnetic radiation in the visible range. This overview begins with an introduction to polyelectrolytes and dyes with their respective definitions, classifications (based on origin, molecular architecture, etc.), and applications in diverse fields. Thereafter, it explores the different possible interactions between polyelectrolytes and dyes, which is the main focus of this study. The various mechanisms involved in dye-polyelectrolyte interactions and the factors that influence them are also surveyed. Finally, these discussions are summarized, and their future perspectives are presented.
聚电解质是带有可电离基团重复单元并与抗衡离子结合的聚合物。最近，聚电解质作为极具前景的高分子材料受到了广泛关注，它们在我们日常生活的几乎每个领域都有应用潜力。染料是另一类化合物，能够与底物相互作用，并通过选择性吸收可见光范围内的电磁辐射来赋予颜色。本综述首先介绍聚电解质和染料，包括它们各自的定义、分类（基于来源、分子结构等）以及在不同领域的应用。此后，探讨聚电解质和染料之间不同的可能相互作用，这是本研究的主要重点。还考察了染料 - 聚电解质相互作用中涉及的各种机制以及影响这些机制的因素。最后，总结这些讨论，并展望其未来前景。
